Application filed October 24, 1921. Serial No. 509,837.

To all whomit may concern:

Be it known that I, ARTHUR E. PEARsoN,

' a citizen of the United States, and resident to provide a sewing machine gatherer havingnovelmeans for gathering the fingers of gloves and other pieces of work so that the same will be in r0 er osition for sewing. I

A further object of the invention is to provide a gatherer which maybe readily and conveniently applied and which may be thrown to an inoperative position when not in use.

A further object of this invention is to provide agatherer which is simple to operate, durable in use and cheap to manufacture.

Other objects and advantages of the in vention will be apparent during the course of the following description. i

In the accompanying drawing forming a part of this application and in which like numerals are employed. to designate like parts throughout the same, i Figure 1 is an edge elevation of the improved gatherer applied.

Figure 2 is a side elevation of the improved gatherer applied.

Figure 3 is a perspective of the improved gatherer. T

Figure 4. is a perspective of the cam or latch embodied in the invention. j

. Figure 5 is a perspective of the gatherer bar detached.

Figure 6 is a fragmentary plan view of the plate of the sewing machine, the View illustrating a portion of the gatherer.

In the drawing wherein for the purposeof illustration is shown a preferred embodiment of the invention, the numeral 10 designates the working plate or bedof a sewing machine especially adapted for doing heavy work.

Thework plate or bed 10 is provided with the usual opening for the reception of the feed rocker 11 having the usual'bar l20'tor operating the same- The upper end of the feed. rocker 11 is provided with the usual 'erer bar to the desired degree.

reference to the needle'l2 connected by means ot a set screw-13 to theneedle carrier 14. 1

i The invention forming the subject matter feed toot which is reciprocated for feeding the material to the proper. position with of this application is in the nature of a gath? 3 i crer especially adapted for cooperating with the feed rocker and the foot of the same gn'esenting the material to he sewed to the needle in proper position. gather-er consistsof a supporting plate 16 having a plurality of openings 17 for the reception of fastening screws 18 by means of which the supporting plate is secured to the work post 19. i

As illustrated particularly in The improved i Figuie .3 v

a. gatherer bar 20 is arranged at one side of the supporting plate 16 and isslidably secured thereto by means of a pivot element 21 extended laterally from thesupporting plate and having its terminal portion screw threaded for engagement withan adjusting nut 22'. Theadjusting nut 22 forms a means whereby the tension of a spring 24 mounted on the pin 21 maybe readily and conveniently varied. for tensioning the gath- When the thumb nut 22 is advanced on the pin 21, the tension of the coiled spring 23 willbe increased, thereby exerting a spring tension on the gatherer "bar 20. Onthe other hand when it is desiredto relieve the tension, the

adjusting nut '22 may be backed up for re ducing the tension exerted by the coiled spring 23. j

The upper portion of the gathereribar 20 extends through the work bed 10 of the machine and is provided with .a longitudinal incision 24l whichreceives the rear portion of the gathering linger 25. The longitudinal incision 24: provides a pair of arms which may be securely engaged with the attaching port-ion oi'the finger 25 by means of a screw bolt 26. Theterminal portion of the finger 25 is. provided along its lower longitudinal edge with a series of teeth 27 adapted to be engaged with the material for gathering the sam i The gather-er bar 20 is rocked by means of a crank 30 havingone' end portion pro vided with a laterally projecting pin 31 extended through an elongated slot 33 in the lower portion of the gatherer bar. The other end portion of the crank 30 is provided with a squared pin 34 adapted to be extend lib ed through the feed rocker and secured" thereto by means, of a nut .35. When the feed rocker 11 of the sewing machine is operated, the crank 30 will also be operated for imparting a, rocking or swinging motion to the gatherer'bar 20." When the gatherer barQO is thus operated, the finger 25 of the same will be engaged with the material mounted upon the bed-v10 for gathering'the material for subsequent sewing. I

Whentlie crank 30' operates the gatherer bar inaclockwise direction the gatherer bar is also elevated by contact with a cam 38 pivotally mounted on a pin or stud 39 carried by the base plate 16, More specifically the cam' 38 pivotally mounted on the pin 59 isprovided with an upwardlyextending lobe 40 arranged in the'path of travel of the downwardly extending ear 41 on the lowerend of the gatherer bar 20. It is thus seen that when the gatherer bar 20 is moved in "a counter-clockwlse direction the curved faceof 'thedepending ear'41 will be engaged with the curved side of the lobe 40 for 1mparting an upward movement to the gatherer bar'and consequently the finger 25 of the same: This upward movement of the gatherer bar takes place simultaneously with the return movement of the gatherer bar at which time the feed is advancing .or moving in'theopposite direction. The cam 38 is rotatable on 'the'pivotpin 39 and is held 'thereon'by means of a collar 44 having a set screw 45 which engages the pin 39. The pivotal movement of the cam 38 is limited by means ofan adjustable stop element/46 arranged in the path of travel of the lobe 40 and adapted to be received with in anotch 47 in the lobe.

The lobe 40 is urged into engagement with the stop element 46 by a coiled spring 48 having connection with an anchoring post49 and a depending apertured ear 50, the said car being formed integral with the cam 38.

On the operative stroke of the finger the depending ear 4i of the gatherer bar engages the flat side of the cam 40 and swings the cam on its pivot 39 against the tension of the coiled'spring 48.

Aretaining spring is connected to the anchoring post 49 and to a stud 56 extending from'one end of the gatherer bar and the said retainin spring 55 serves as a means for urging tie gatherer bar downwardly into engagement with the material and to its operative position. However, the coiled spring 55 permits the gatherer bar to be elevated-when the depending ear 41 is engaged with the inclined sides of the cam lobe 40.

It will be seen that when the feed rocker moves about the longitudinal axis of the b'ar'l20i the crank 30 will be oaerated for impartinga rocking motion to t e gatherer bar-20. When the gatherer bar 20 is moved gatherer bar.

in a counter-clockwise direction it is on the return stroke and is therefore elevated by the engagement of the depending ear 41 with the lobe 40. Then the depending ear 41 passes over the lobe 40 the finger 25 drops onto the material and the movement as the same may be moved to an inopera-' tive position by means of an adjusting rod 60 connected to the gatherer bar by means of an ear or hinge member 61 which incidentally is rotatably connected to the gatherer bar. More particularly the gatherer bar is formed with a longitudinal slot 68 which receives the attaching pin of the ear or hinge member 61.

By reason of hingedly connecting the adjusting rod 60 to the gatherer bar the adjusting rod does not in any way interfere with the vertical or rocking motion of the The adjusting rod may be held in a set position by means of a thumb nut'66 arranged above the plate or bed 10. A hand lever 68 is connected to the adjusting rod 60and forms a means whereby the gatherer bar may be drawn away from the needle 12.

'In other words the adjusting rod 60 and the member 20 may be held'in a set position by tightening the thumb nut 66. It is thus seen that the atherer may be positioned out of the way when necessary;
